column and index definitions. When TimesTen restores a table in a new data store, it also restores the table’s indexes.

Note: The ttMigrate utility cannot migrate data stores across different hardware platforms. For example, you cannot migrate a Windows data store to a Solaris data store. The release of ttMigrate must also match the release of the data store you are copying from or to. In the example in this section, use ttMigrate of the older version to save the tables of the original data store to disk files and use ttMigrate of the new version to migrate the files into the tables of the new data store.

For a description of the ttMigrate syntax and usage, see "Utilities" in the Oracle TimesTen In-Memory Database API Reference Guide.

To migrate a data store from different versions:

1.Use ttMigrate to save the tables in the older version data store to a disk file.

If, for example:

•A TimesTen 6.0 data store is called Sales600;

•The data file you wish to use is called sales.dat; and

•TimesTen 6.0 is installed in /opt/TimesTen60 on UNIX platforms or C:\TimesTen\TimesTen60 on Windows.

On Windows, use:

C:\ > ”C:\TimesTen\tt60\bin\ttMigrate” -c DSN=Sales600 sales.dat

On UNIX, use:

%/opt/tt60/32/bin/ttMigrate -c DSN=Sales600 sales.dat

2.Use ttMigrate to restore the saved tables in the new data store.

3.Create a new data source name, Salestt70 for the TimesTen 7.0 data store, and import the 6.0 data store:

If, for example:

• TimesTen 7.0 is installed in /opt/TimesTen/tt70 on UNIX platforms or C:\TimesTen\tt70 on Windows.

On Windows, use:

C:\ > ”C:\TimesTen\tt70\bin\ttMigrate” -r DSN=Salestt70 sales.dat

On UNIX, use:
